Incoming Call Processing Method for Dual Mode Terminal and Dual Mode Terminal Thereof

1. An incoming call processing method for a dual mode terminal which has a first mode card and a second mode card, comprising: the first mode card of the dual mode terminal receiving an incoming call signal; and if the dual mode terminal determines that the incoming call signal meets a switch condition, switching the incoming call signal to the second mode card automatically; wherein, when the switch condition comprises a heterogeneous network switch condition and a network signal quality switch condition, the step of if the dual mode terminal determines that the incoming call signal meets the switch condition, switching the incoming call signal to the second mode card automatically, comprises: when a priority of the heterogeneous network switch condition is higher than a priority of the network signal quality switch condition, the dual mode terminal inquiring a mobile number home network list stored locally, obtaining a home network of a calling number; comparing the home network of the calling number with a home network of a called number; and if those two are inconsistent, switching the incoming call signal to the second mode card automatically; and when the priority of the network signal quality switch condition is higher than the priority of the heterogeneous network switch condition, if the dual mode terminal determines that a current network environment signal quality of the first mode card is lower than a preset first threshold value and a current network environment signal quality of the second mode card is higher than a preset second threshold value, switching the incoming call signal to the second mode card automatically; if the dual mode terminal determines that the current network environment signal quality of the first mode card is higher than the preset first threshold value and the current network environment signal quality of the second mode card is higher than the preset second threshold value, comparing the obtained home network of the calling number with the home network of the called number; if those two are inconsistent, switching the incoming call signal to the second mode card automatically.

2. The method according to claim 1 , wherein, before the dual mode terminal compares the obtained home network of the calling number with the home network of the called number, the method further comprises: the dual mode terminal inquiring the mobile number home network list stored locally, and obtaining the home network of the calling number.

3. The method according to claim 1 , wherein, before the dual mode terminal determines that the incoming call signal meets the switch condition, and then switches the incoming call signal to the second mode card automatically, the method further comprises: the dual mode terminal opening an intelligence answering function.

4. A dual mode terminal, which has a first mode card and a second mode card, comprising hardware performing instructions stored in a non-transitory computer readable medium which executes steps in following modules: a conversation module, configured to: receive an incoming call signal by using the first mode card; and a switching module, configured to: if determining that the incoming call signal meets a switch condition, switch the incoming call signal to the second mode card automatically; wherein, the switching module is configured to: when the switch condition comprises a heterogeneous network switch condition and a network signal quality switch condition, when a priority of the heterogeneous network switch condition is higher than a priority of the network signal quality switch condition, inquire a mobile number home network list stored locally, obtain a home network of a calling number, and compare the home network of the calling number with a home network of a called number; if those two are inconsistent, switch the incoming call signal to the second mode card automatically; when the priority of the network signal quality switch condition is higher than the priority of the heterogeneous network switch condition, if determining that a current network environment signal quality of the first mode card is lower than a preset first threshold value and a current network environment signal quality of the second mode card is higher than a preset second threshold value, switch the incoming call signal to the second mode card automatically; if determining that the current network environment signal quality of the first mode card is higher than the preset first threshold value and the current network environment signal quality of the second mode card is higher than the preset second threshold value, compare the obtained home network of the calling number with the home network of the called number; if those two are inconsistent, switch the incoming call signal to the second mode card automatically.

5. The dual mode terminal according to claim 4 , further comprising: a storage module, configured to: store a mobile number home network list of a corresponding relationship of a mobile number and a home network thereof.

6. The dual mode terminal according to claim 5 , wherein, the switching module is configured to: before comparing the obtained home network of the calling number with the home network of the called number, inquire the mobile number home network list stored by the storage module, and obtain the home network of the calling number.
